UI for Automation->Scripts does not load

Product: PowerShell Universal
Version: 5.6.9

Hi everybody,

I have a pretty similar issue to this post Help - Created a file for a script. Now UI won't load

Since I have Updated PU to Version 5.6.8, the Scripts Page only shows a Loading circle and does not finish loading the Scripts. I was wating for V 5.6.9, but still the same issue. However, I am still able to access the Scripts through the “Jobs” Page and over Settings→Files.
Atm I am not shure, where else to look at. For me, the Logs do not show a special kind of Error, related to this issue. So I am a littlebit lost at the moment.

I was Upgrading from 5.2.3 .

Running on IIS.
